Supergirl Movie Special is the official comic adaptation of the 1984 movie. Published in October 1984 (with a cover date of February, 1985), it was written by Joey Cavalieri and penciled, inked and colored by Gray Morrow. Jose Luis Garcia Lopez provided the cover art.
Kara Zor-El, Superman's kid cousin, is one of the denizens of Argo, a Kryptonian city which survived its planet's holocaust and now drifts aimlessly around the space. One day, Kara's friend and mentor Zaltar "borrows" the Omegahedron, a matter-transmuting artifact which keeps Argo's life support systems running, so he can create and see a real organic tree with his own eyes before leaving for Earth. However, Alura walks into his den as he is showing Kara the Omegahedron, and Zaltar is forced to lend his matterwand to Kara to keep both women distracted as he hides the stolen device hurriedly.
Unfortunately, Kara playing with the wand accidentally opens a breach into the forcefield surrounding Argo City, and the Omegahedron is sucked into the space. Blaming herself for the loss, Kara "borrows" Zaltar's space pod and sets out on a quest in search of the device before her city run out or power.
Her quest leads her to the planet which her cousin calls home, where an ambitious and powerful witch called Selena has found the Omegahedron.
- Actionized Adaptation: The comic-book, working off an earlier version of the script, toned down many of the Midvale scenes in favor of more action, including a fight with a shadowy version of Selena in lieu of the film's gigantic demon.
- Adaptation Deviation: Rather than stealing Nigel's wand to turn him into an old man, as she did in the original film, Selena uses the Omegahedron to age him artificially.
- Adaptation Dye-Job: In the original film, Kara's parents Zor-El and Alura were a brunette man and a blonde woman. In the comic-book adaptation, Zor-El is a redhead and Alura has reddish-brown hair.
- Adapted Out: The film scene where a pair of truckers try to harass Supergirl is cut out.
- Aliens in Cardiff: Kara's pod lands close to the sleepy town of Midvale shortly before a witch decides to take it over to build her power base.
- Aliens Speaking English: Justified. Despite being an alien Kara can speak, read and write in English because her parents had monitored Superman's activities in Earth and learned the language.
- Big Bad: Selena takes hold of the Omegahedron, a transmuting-matter device which usually serves as Argo City's life support system, and she uses its power to take over one whole town.
- Bridal Carry: Non-romantic example. Zor-El carries his daughter Kara in his arms after saving her from being dragged out of Argo City's borders and into the vacuum of space.
- But Now I Must Go: After defeating Selena and restoring Midvale to normal, Supergirl says goodbye to the people she met and streaks into space to go back to her hometown.

- Contrived Coincidence: When the Omegahedron gets thrown into space, it randomly drifts towards Earth and crashes into the ground next to a black magic practitioner with world domination aspirations.
- Crystal Spires and Togas: Argo City looks like a humongous, glowing-white, drop-shaped diamond floating in space. Their inhabitants wear bright robes and flowing capes.
- Disaster Dominoes: The events which lead to the battle between Supergirl and Selena are as follows: Zaltar steals a matter-replicating device so that he can see lifelike vegetation. When he is nearly caught by Alura, he gives Kara his matterwand to keep her mother distracted as he subtly kicks the Omegahedron away. The ball-shaped device rolls near Kara when she is playing with the wand. Kara creates an insect, gets scared, and shoves it away. The insect then crashes into the city's barrier, and the Omegahedron is sucked through the crack. Kara blames herself, gets into Zaltar's space pod and pursues it until Earth, where it is found by Selena.
- Does Not Know His Own Strength: Kara emerges out of her pod after landing on Earth and starts exploring her surroundings. Feeling marveled by world's nature, she picks a rock, unaware of her newly-gained super-strength, and gets shocked when the stone unexpectedly shatters into a million bits.Kara: "It's so hard...So rough to the touch! I wonder if...I—I broke it! But...I was never that strong before!"
- Doppelgänger Spin: Selena creates a bunch of copies of herself to surround Supergirl and prevent her from saving Ethan.

- The Greatest Story Never Told: Kara destroys both Selena and her world-conquering scheme before heading back home. However, she was only seen by three people who promised to not say a word to anybody about her. The people of Midvale never knew their savior, and they never knew why Selena simply and suddenly vanished without a trace after arrogantly taking over the town.
- Hoist by His Own Petard: As dodging a demonic shadow-copy of Selena, Supergirl takes Nigel's advice to turn the witch's powers against her. Kara creates a cyclone that traps Selena and the demon together, and since it now has nothing else to go after, it turns on Selena, who fears her own monstrous "reflection".

It's my fault the Omegahedron ins gone...and it's up to me to get it back!"

While this is true, Supergirl is also aware that Bianca was not in the slightest bit conflicted about said orders, so she does not lift a finger to help her enemy's right-hand woman.
- Karma Houdini: Nigel, a sorcerer who owns trinkets of "unspeakable evil", is the one who taught Selena black magic. He also helps Selena kidnap Ethan, but he takes no direct action against Supergirl, so Nigel simply walks away after the climax. He even gets his youth restored when Selena's aging spell is undone.
- Kryptonite Factor: There is not Kryptonite to be found anywhere in the story, and magic takes its place as the tool used by the villain to hurt the Kryptonian hero.

Unfortunately for her, Ethan sneaks out of her den as she is busy, and he stumbles into Linda Lee.Selena: "Now he who drinks the water will fall in love with the first person he sees, as long as the spider is confined, or one day goes by!"
Selena: "No! NO! He looked at that little twerp and fell in love with her!"

As soon as Nigel gives her what she wants, Selena transforms him into an old man out of sheer spite and ditches him once again.

By this point, though, Nigel is so thoroughly sick of her antics that he turns on Selena and helps Supergirl beat her.
